<p>一般来说，您需要针对特定类型的反馈使用特定状态：</p>
<ul>
<li><code translate="no" class="notranslate text-nowrap">false</code>（表示无效状态）非常适合存在阻塞或必填字段的情况。用户必须正确填写此字段才能提交表单。</li>
<li><code translate="no" class="notranslate text-nowrap">true</code>（表示有效状态）非常适合在整个表单中都进行逐字段验证并希望鼓励用户遍历其余字段的情况。</li>
<li><code translate="no" class="notranslate text-nowrap">null</code> 不显示验证状态（既不有效也不无效）</li>
</ul>
<p>要在 <code translate="no" class="notranslate text-nowrap">&lt;b-form-radio&gt;</code> 上应用上下文状态图标之一，请将 <code translate="no" class="notranslate text-nowrap">state</code>【状态】属性设置为 <code translate="no" class="notranslate text-nowrap">false</code>（对于无效），<code translate="no" class="notranslate text-nowrap">true</code>（对于有效）或 <code translate="no" class="notranslate text-nowrap">null</code>（无验证状态）。</p>

<p>使用这些上下文状态来表示表单控件的状态仅提供基于颜色的可视指示，而不会将其传达给辅助技术的用户（例如屏幕阅读器）或色盲用户。</p>
<p>确保还提供了备用状态指示。例如，您可以在表单控件的 <code translate="no" class="notranslate text-nowrap">&lt;label&gt;</code> 文本本身中包含有关状态的提示，或者通过提供其他帮助文本块（即 <code translate="no" class="notranslate text-nowrap">&lt;b-form-invalid-feedback&gt;</code> ）。专门针对辅助技术，还可以为无效的表单控件分配一个 <code translate="no" class="notranslate text-nowrap">aria-invalid="true"</code> 属性（请参见下文）。</p>

<p>当 <code translate="no" class="notranslate text-nowrap">&lt;b-form-radio-group&gt;</code> 具有无效的上下文状态（即 state = <code translate="no" class="notranslate text-nowrap">false</code> ）时，您可能还希望将 <code translate="no" class="notranslate text-nowrap">&lt;b-form-radio-group&gt;</code> 属性 <code translate="no" class="notranslate text-nowrap">aria-invalid</code> 设置为 <code translate="no" class="notranslate text-nowrap">true</code> 。</p>
<p>支持的 <code translate="no" class="notranslate text-nowrap">aria-invalid</code> 值是：</p>
<ul>
<li><code translate="no" class="notranslate text-nowrap">false</code>（默认）未检测到错误</li>
<li><code translate="no" class="notranslate text-nowrap">true</code> 该值验证失败。</li>
</ul>
<p>如果 <code translate="no" class="notranslate text-nowrap">state</code>【状态】属性为 <code translate="no" class="notranslate text-nowrap">false</code> ，则将 <code translate="no" class="notranslate text-nowrap">aria-invalid</code> 自动设置为 <code translate="no" class="notranslate text-nowrap">true</code> 。</p>
